Good news! I actually decided to leave him alone for a couple days. I figured I'd let him ask when I wanted the gun.
Low and behold a couple hours ago he asked me when I wanted to pick it up!

I feel bad for him. He's being forced to get out of shooting due to a severe hearing problem. I figured I'd let him take his time.
He told me, this was one of his favorite shotguns. I'm a happy camper.
